SPECIFICATION forming part of Letters Patent No. 576,588, dated February 9, 1897.

Application ined February 1,1396. serialNo. 577,659. (No meant.)

T0 all wit/0m z3 may concern:

Beit known that I, UHARLEYA. KULLBERG, a citizen of the United States, residing at Hawick, in the county of Kandiyohi and State of Minnesota, have invented certain new and useful Improvements in Motor-Driven IIa-rvesters; and I do hereby declare the following to be a full, clear, and eXac-t description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to harvesters, and has for its object to improve the construction of the same with a view of giving increased efficiency and making practicable a machine of very large capacity.

To these ends my invention comprises the novel devices and combinations of devices hereinafter described, and deiined in the claims.

It is thought that it will assist the reader in distinguishing the broad or generic features of my invention from the more specific details of construction to note in advance the following facts:

In adapting the machine for heavy work I provide a motor which I preferably mount on the machine -frame, and provide variable drives extending` from the motor to the traction-wheelsof the machine and to the harvesting mechanism. These drives are arranged to operate the respective devices driven thereby, either simultaneously or independently, under the action of the motor.

The motor which I prefer to employ is an ordinary gas or gasolene engine. In connection with this gas or gasolene engine and the drive or drives extending therefrom I provide a reversing device, by means of which the direction of rotation of the traction-wheels of' the machine may be reversed to back up the machine. I also provide raising and lowering connections, which are applied to the 0pposit-e ends of the harvester-platform and which are adapted to be operated to raise the ends of said platform, either simultaneously or independently, at will.

So far as the broad principle of my variable drive or driving mechanism above referred to is concerned it is not necessary that the samebe used in connection with a motorwhich is carried by the machine and servesto pro- It may be here remarked that the expression harvesting mechanism, as used throughout this specication and the claims, is used in a sense broad enough and is intended toinclude any one or more of the devices used in the act i of harvesting, namely, the binder, the cutting device, the canvases or carriers, and the reel.

My invention also comprises certain minor details of construction, which will be hereinafter described, and defined inthe claims.

The preferred form of my invention is illustrated in the accompanying drawings, therein like letters referring to like parts throughout the several views.

Figure l is a plan view of the machine, some parts being removed. Fig. 2 is a side elevation looking from the right-hand side of the same, some parts being also removed. Fig. 3 is a diagram view showing certain parts of the machine, looking from the left-hand side of the machine. Fig. 41s a detail showing a movable fulcrum-block and support for one of the raising and lowering levers, some parts being broken away. Fig. 5 is a transverse vertical section taken on the line 5v5 005 of Fig. 4, looking toward the rear. Fig. (i is a horizontal section taken through a portion of the left end of the machine on the line 006 c6 of Fig. 8. Fig. 7 is a detail view in perspective, showing parts of one of the variable-speed driving mechanisms constituting my invention. Fig. 8 is a horizontal section also showin g parts of said variable-speed driving mechanisms. Fig. 9 is a detail in side elevation, showing the latch devices for controlling the raising and lowering connections of the harvester, some parts being broken away. Fig. l0 is a transverse section taken Vsubstantially on the line w10 x10 of Fig. 9; and Fig. l1 is a detail view, in right side elevation, showing the pivotal connection between the right member of the raising and lowering levers and the platform-segment.

Referring especially to Figs. l and 2, ct indicates the platform-frame, a the endless platform carrier or canvas, a? the sickle, and 0,3 the sickle-pitman driven from crank-disk a4 on the crank-shaft a5, all of the ordinary harvester construction. In alike manner to the ordinary harvester the right end of the platform d is provided with apair of rigidlysecured loop-segments a, having on their interior rear edge raek-teeth a7. Vith these rack-.teeth a7 engage a pair of pinions as, both of which are rigidly secured on a short shaft a". It is on this short shaft a9 that the bullwheel of the ordinary harvester is mounted; but, as will later appear, I pivotally secure the forward end of the right member of the lifting-levers used in my present invention to this shaft ai.

In my present invention, for the purpose of carrying and operating the harvester proper, I employ a large traction-truck, upon which is mounted a gas-engine or other suitable motor, provided with driving connections for operating both the tractionwheels of the truck and the cutting and binding mechanism of the harvester.

As shown, the traction-truck comprises a large skeleton-like fram e l), in the forward portion of which is loosely mounted apair of laterally-spaced traction-wheels b', and in the rear portion of which frame is pivotally mounted a ru dder-wheel b2. Rudder-wheel b2 is directly mounted in a swiveled bracket b3, the stem portion of which projects upward through a suitable seat in the rear end of said truckframe b and is provided with a sheave b4.

The rudder-wheel b2 is moved, in the act of steering the traction-truck, by means of a vertical shaft b5, mounted in a bracket D6 on the truck-frame b, provided at its upper end with a hand-wheel bl and at its lower end with a small sheave bs andby an endless cable b, wrapped around said sheaves b4 and bs.

As shown in the accompanying drawings, the harvester-platform d is supported from the traction-truck l), with freedom for both vertical and pivotal adjustment with respect thereto, by means of a pair of longitudinallydisposed levers c and d. Of these levers the lever c, which is the longer of the two, has its forward end pivoted on the pinion-shaft d and is fulcrumed at its intermediate portion on a pin c', carried by an adjustable fulcram-block c2, mounted for vertical adjustment in a bracket c3, rigidly secured tothe forward right-hand corner of the truck-frame b.

It will be noted that the bracket c3 is pro vided with vertical slots c4 in its sides, through which the projecting ends of the fulcrum-pin c work, to hold the block in position. The vertical adjustment of this fulcrum-block c2 is effected by means of a screw-rod ci", having screw-threaded engagement through the upper head of the bracket c3, attached at its lower end by means of a swiveled connection c to the said block c2, and provided at its upper end with a hand-wheel c?.

The pinion-shaft a9 may be locked to the forward end of the lever c and thereby held in any adjusted position with resp/eet to the segments a and a7 by means of a worm-gear c, rigid on the shaft a9, and engaged by a worm c" on the end ol' a rod cw, which rod is mounted for rotary but fixed against endwise movement in bearings c, secured to said lever c.

The lever d is much shorter than the lever c and is fulerumed at its intermediate por tion in a manner substantially identical with that just described in connection with said lever c. In this case d indicates the fulcrumpin passing through said lever cl and an adjustable fulcrum-block cl2, with its projecting ends working in vertical slots d3, formed in the sides of the bracket d'1, which bracket in this case is rigidly secured to the forward left-hand corner of the truck-frame b.

d5 is a screw-rod working through the bracket d'1 and swiveled to the fulcrumblock d2.

The forward end of the lever d is pivoted on a proj eeting pin (Z6, carried by a vertically movable plate L17, loosely mounted in the anged bracket CZ, secured to the left end of the platform-frame a. rl`he rear liange of the bracket (Z8 is provided with rack-teeth CZ, with which engages a pinion d10, formed integral with a worm-gear du, both of which are loosely mounted on the stud or pin t G, between the lever CZ and the plate d?.

d12 is a worm carried at the end of a rod (Z13 and engaging the worm-gear du. The rod Z13 is mounted for rotary but fixed against endwise movement in bearings d, carried by the lever d. By this means, as is obvious, the left end of the platform may be vertically adjusted with respect to the forward end of the lever CZ by turning the rod Z13 and worm CP2. It will also be seen that the platform frame and parts carried thereby may be vertically moved from both ends by the movement of the levers c and CZ- on theirfulcrums. This is the ordinary and quickest way of adjusting the same, and I provide means for facilitating this movement, which will now be described.

On a platform or deck bw, which covers the rear portion of the truck-frame b, and just forward of the drivers seat Z911, I mount three controlling-levers ff'f2. The central member f of these levers works between the blades f3 of a slotted or bifurcated latch-arch bracket f4 and has its hub pivotally mounted in a bearing f5, located at the radial center of said arch-blades f3. The bracket f4 is rigidly secured to the deck bw. The hub of the lever f carries at its end bifurcated latch-arches f6 and f7, between which the levers f'f2, respectively, work. The levers f j" f2 are provided with hand-operated spring-latch pawls f8 fffl), which cooperate with their respec-A tive latclrarches to secure said levers wherever set. The outside levers f f2 are rigidly secured, respectively, on the ends of transverse shafts f j, mounted in suitable bearingsfl, secured on the deck b, with their centers in line with the pivotal center of the hub of the lever f. 1

The shaft f12 extends to the right of the IOO IIO

machine and has secured to its outer end an arm f14, the free end of which is attached to the rear end of the lever c by means of a slotand-pin connection f11.

The shaft f11 extends to the left of themachine, and has secured to its outer en d a short lever fw.

f11is a bell-crank lever pivoted at its fulcrum on a bracket `761s, projecting from and rigidly secured to the frame b. The lower arm of this bell-crank f is attached by means of a slot-and-pin connection]C19 to the rear end of the lever d, While the upper arm of the same is connected by means of a link f2 with the free end of the lever or arm f1,

In virtue of the levers and other raising and lowering connections above described the following actions are made possible: The operator, by drawing` the free end of the lever f toward the rear of the machine, will carry the latch-arches fvand f7 also to the rear, and hence, through the levers f and f2 and intermediate connections, will force the rear ends of the levers c and c7 downward, thereby simultaneously raising both ends 0f the platform-frame a. Again, by drawing the lever f2 toward the rear the rear end of the lever c will be lowered and the right end of the platform-frame a will be raised without affecting the left end of the platform. On the other hand, if it is the lever f that is drawn to the rear the rear end of the lever c7 will be lowered and the left end of the platform-frame a will be raised.

In all of the above actions it will be notedr that the latch-arches f3 j4 serve as a base of resistance to retain all of the levers fff2 in position.

The above arrangement of levers and lifting connections, in virtue of which the platform and cutting devices of the harvester may be adjusted either simultaneously or independently from its opposite ends, is an extremely desirable construction. The purposes accomplished by means of these variable adjustments will be-readily understood to all persons familiar with the handling of In brief, it permits the platform and cutting devices to be set longitudinally parallel with the ground, or at an angle thereto, and then to be moved vertically without changing the angle or parallelism of said platform. o

Returning now to the motor carried by the truck-frame and the series of independent driving connections therefrom to the traction- Wheels and to the harvesting devices of the machine, attention is directed first to Figs. l and 2. As here shown, l employa gas, gasolene, or oil engine, of any ordinary standard type suitable for the purpose, of which g is the cylinder; g", the piston-rod; g2, the crankshaft g3, a pair of fly-wheels secured on the opposite ends of the crank-shaft g2; and g4 is the bed or frame, which bed is bolted to the top of the deck Z910, forward of the levers f f f2. The valve-gear and certa-in other parts of the engine have been omitted from the drawings, but it will be understood, of course, that they may be of the ordinary construction. For use in connection with this gasolene-engine I have shown an ordinary cold- Watertank g5 and gasolene-tank gs, which are secured to the deck 1910, `as shown in Figs. 1 and 2.

`Before proceeding farther, it may be well to remark that all of the sprocket-chains illustrated in connection with the following drives or driving mechanisms have, for the sake of clearness, been indicated on the drawings simply by dotted lines.

The independent guides which extend one from each of the drive-wheels g3, respectively, to the traction-wheels and to the harvesting devices are in the following respects substantially alike, and similar parts will be marked with the same letters. Referring to these parts, 7c indicates a pair of short shafts which are located axially in line with the engine crank-shaft g2 and extend one to the right and the other to the left from said crankshaft and are loosely mounted in rectangular bearing-frames 7c', rigidly supported one from each side of the truck-frame o. These shafts 7c are adapted to be independentlyconnected to their respective cooperating flywheels g3 by means of friction-clutches. As shown, these friction-clutches comprise each a sliding head k2, secured to the shaft 79 by means of a groove and feather, (not shown,) friction-shoes 7c3, engageable with the interior of the rim of the iiy-wheel g3, and links 7c4, connectingsaid shoes 7c3 with said sliding head 7a2. By moving the sliding head 7a2 toward the ily-wheel g3 the shoes 7.93 will be forced into frictional engagement with the rim of said illy-wheel and the shaft 7.: will be caused to revolve. As is evident, the outward movement of said sliding head 7a2 will retract the shoes 7c3 and cause the shaft 7c to remain at rest. The movements of these sliding heads 7a2 are preferably controlled by means of shipper-levers 765, having the ordinary pin-and-groove connection therewith. As shown, these levers 765 are pivoted to the framework at k6 and are held wherever set by means of latch-plates k7.

Returning to the shafts 7s, 79S indicates a series of half-clutches which are fixed on each of said shafts by means of pins or otherwise. 7c9 indicates corresponding series of sprocketwheels loosely mounted on said shafts 7c and provided with half-clutches cooperating with the half-clutches ks.

7610 indicates a pairof coun ter-shafts located one in advance of and parallel to each of the shafts 7c. These shafts 7010 are also loosely mounted in the rectangular bearing-frames 7c and are provided with fixed half-clutches 7511, corresponding to the fixed half-clutches hs on the shafts 7s. k12 indicates corresponding series of sprocket-wheels loosely mounted on IOO IIO

said shafts 7610 and provid ed with half-clutches v lly reference to Fig. l it will be noted that the series of sprocket-wheels L12 on the shafts 7h10 increase in size from the center of the machine outward.

The sprocket-wheels 7o and 7d?, which are located in line with each other longitudinally of` the machine, are connected in pairs by means of sprocket-chains L13. It will thus be seen that the inner pairs of sprocket-wheels 7; L12, when thrown into action, will drive the counter-shafts 7am at a higher rate of speed than would any of the corresponding pairs of wheels that are located farther out.

lThe means which I have shown for throwing any one of the pairs of sprocket-wheels 7:9 L11 into action at will is as follows: The st )rockct-wheels 71:11 and 7x12 are provided on their hubs with annular collars L11, which work between keeper-brackets 751'", carried by shipper-bars 7'1". These shipper-bars, it will be noted, are perforated and slide loosely on the shafts 7c and L10, and the keeper-brackets 7&15 carried thereby also connect said sprocketwheels 791) and 71112 in pairs. Hence, by moving the shipper-bars 71:1 laterally any pairof sprocket-wheels 7e 7h12 may be engaged with the cooperating pairs of fixed half-clutches 76S 7r11. The independent movement of these shipper-bars 7916 is accomplished as follows:

7t11 are rock-shafts in parallel arrangement longitudinally of the machine, mounted in the rectangular bearing-fram es 7D" and in bearing-blocks 7518 at the rear of the truck-frame b. These rock-shaftst;1T correspond in number to the number of shipper-bars 7s1Gand cooperate one with each of the saine. The rods L17 or rock-shafts are provided with upwardlyextending pairs of parallel arms 7cm, which are connected by means of slot-and-pin connections 71520 with the opposite ends of the shipper-bars. At their rear ends the rockshaftsk11 are provided with inturned levers L21, which are held in either of two positions by means of notched lock-plates 7.522.

Vith the above construction it is obvious that the operator, from the seat 7111, may readily move any one of the levers L21, and through the rock-shafts 7c, arms k1, and shipper-bars 7510 may render operative or inoperative at will any pair of sprocket-wheels 7c 7512, and hence may vary at will the speeds of the shafts R10 with respect to each other or to the speed of the engine.

Of the two independent drives above described it may be well to observe at this Ypoint that the sprocket wheel and chain conent drives are essentially different in construction and will be described separately.

Referring to the drive to the cutting devices, it will be noted, by reference to Fig. l,

that the inner end of the variably-driven counter-shaft 7010 is provided with a rigid sprocketwheel 7:23.

i321 is a transverse counter-shaft mounted in bcarin gs 735, fixed to the rear right end of the platform-frame a and provided with a bevelwheel 7h26 at its right end and at its left end with a sprocket-wheel 71:21, located in line with the sprocket-wheel 7523.

7a23 indicates a sprocket-chain passing over the wheels 7523 and 7W.

It will be noted that the shaft 7&1 on the platform-frame a serves as a common shaft from which all parts of the harvestii'ig mechanism-t'. c., the binder, (not shown,) the sickle, the canvases, and the reel (not shown)-are driven, and that this shaft 7521 is driven directly from the right-hand member of the counter-shafts 7t10. The slack of this chain is automatically taken up by means of a sprocket-like chain-tightener 7J, mounted on one of the cross-beams of the truck-frame h.

7a3() is a bevel-wheel carried on the rear end of the pitman crank-shaft a5 and in engagement with the bevel-wheel 7a2 on the shaft 7621.

Complete driving connections between the ily-wheels giE of the engine and the harvesting mechanism have now been described, and since, as already clearly pointed out, the shaft 7t10 may be variably driven, it will of course necessarily follow that said harvesting mechanism may also be variably driven.

7c31 indicates a sprocket-wheel on the rear end of the pitman-shaft a5, just inward of the bevel-wheel 75). This sprocket-wheel 7J serves to im part motion to the binding mechanism. (Not shown.)

The binder or binding mechanism, it will of course be understood, will be carried by and supported from the platform-frame a in the ordinary manner. The binder being driven from the variable drive, as above described, it will of course follow that the binder and binding mechanism of the same will be driven at a speed proportioned to the speed of the cutting devices.

Returning now to the variable drive to the traction-wheels, it will be noted, by reference to Fig. 1, that the shaft L11) is near its inner end provided with a ri gidly-securcd sprocketwheel 7e3?. 71:13 is a divided shaft mounted in suitable bearings in the truck-frame b and provided at its opposite ends with pinions 7611, engaging with internal gear-teeth 612, formed on the interior rims of Ithe traction-wheels b. The sections of the shaft 7633 are connected by means of an ordinary compensating-gear 701, having a main sprocket-wheel 7a3, located in line with the sprocket-wheel70112. 7531 indicates a sprocket-chain passing over the sprocketwheels 7532 7J.

A complete variable drive between the engine and the traction-wheels has now been described.

Inasinuch as a gas-engine cannot be reversed I find it necessary, in the particular arrangement described, to provide a revers- IOO IIO

ing device by means of which the tractionwheels may be reversed and the machine backed up. As shown, this reversing device comprises the following` mechanism: p indicates a sprocket-wheel looselyT mounted on the inner end of the right-hand member of the shafts k just inward of the rectangular frame lc. This wheel p is provided with a half-clutch, which is adapted to be engaged by a sliding half-clutch p', mounted for` sliding movementon said shaft 7c by means of a groove and feather. (Not shown.) p2 is a spur-gear loosely mounted on the inner end of the left-hand member of the counter-shafts 7010. This spur-gear p2 is provided with a half-clutch, which is adapted to be engaged by a sliding half-clutch p3, mounted for sliding movement on said counter-shaft 7610 by means of a groove and feather. (Not shown.)

zo p4 is a transverse counter-shaft mounted in bearings pi on the frame b and provided at its right end with a sprocket-wheel p6 in line with the sprocket-wheel p and at its left end with a spur-wheel p7, engaging the spurwheel p2. p3 indicates a sprocket-chain passing over the sprocket-wheels 17 and p6. p" and p1" indicate shipper-levers pivoted, respectively, at p and p12 to the frame Z) and having the ordinary pin-and-groove connections, -respectively, with the sliding halfclutches p and p3. The forward ends of these shipper-levers p9 and p10 are connected by a link p13. The free end of the lever p9 projects rearward to a point opposite the drivers seat, at which point it is secured to a hand-lever p14. The operation of this reversing device is apparent. Before throwing the reversing device into action the variable-driving devices should be thrown out of action. Then by moving the rearl end of the lever p9 toward the right both of the halfclutches p and p3 will be simultaneously thrown into action with the half-clutches of the wheels p and p2, respectively, and the reverse motion of the traction-wheels thereby effected.

Attention is here recalled to the frictioncluteh devices k2 k3 7a4 used in connection with the fly-wheels 7c3. In all of the abovedescribed driving actions, either forward or reverse movement, these friction-clutches serve to gradually apply the driving power to the different parts of the machine, and thereby eliminate the possibility of breakage from sudden applications of the driving power. In the reversing action only the right-hand section-clutch is operative'.

In the accompanying drawings no special means has been shown for controlling the tilting movement or dip of the platform a, but it will be understood, of course, that any means suitable for this purpose might be employed.

The truck-frame l) is shown as trussed and braced by means of a vertical standard Z113, rising from said frame b, and stay-rods om,

running `from the top of said post cl3 and connected to different parts of said frame b. p The variable drives or driving mechanisms whereby the harvesting mechanism may be driven at different rates of speed with respect to any given speed of advancing movement of the harvester is thought to be a novel and valuable improvement in harvesting machinery, and is of especial value when used in connection with harvesters of very large capacity, such as the motor-driven harvester here shown. It enables the binding mechanism, as well as the cutting and delivery devices, to be run at a very high rate of speed when very heavy grain is encountered, so that the grain may behandled and bound with such increased rapidity that the determined and desired rate of advancing movement of the machine need not be interfered with. Again, instead of increasing the speed of the harvesting devices on encountering heavy grain the advancing speed of the machine may be decreased, or at one and the same time the speed of the harvesting mechanism may be increased and the advancing movement of the machine decreased. Obviously this variable drive might be applied to mowers and similar machines as Well as to grain-harvesters.

It will be understood, of course, that various alterations in the details of construction of my invention may be made without departing from the principles of the same. 'For instance, the variable drives instead of being entirely independent of each other throughout their entire extent, as shown, might have certain of their parts in common and only the variable parts arranged independent of each other. Again, as is obvious, the drive might be applied to one or more of the tractionwheels.

lV hat I claim, and desire to secure by Letters Patent of the United States, is as follows:

I. In a harvester or similar machine, the combination with the traction wheel or wheels and harvesting mechanism, of a motor mounted on the machine-frame and independent variable drives extending from said motor, one to said traction-wheels, and the other to said harvesting mechanism, whereby the speeds of said traction-wheels and harvesting mechanism may be varied with respect to each other and to said motor, substantially as described.
